122,53 €Kizer Madrac CL AirTi Gray-Black Vortex Micarta, Gray PVD Stonewashed M390 by Matteo Pignatelli – an ultralight EDC folder
The Kizer Madrac CL AirTi K3693ACS4 is a slim EDC folding knife designed by Matteo Pignatelli, combining the lightweight AirTi construction with a Gray-Black Vortex Micarta handle. The M390 steel Sheepsfoot blade features a gray PVD coating with a stonewashed finish, giving this version a more technical and utilitarian character.
Skeletonized liners made of Ti-6Al-4V help reduce weight while maintaining high handle rigidity. The Kizer Clutch Lock™, thumb stud, and ball bearings ensure smooth operation, while the reversible tip-up clip allows you to adjust the carry style for either right- or left-handed use.
M390 – High Edge Durability
The blade is made of M390 steel, which combines high wear resistance, very good corrosion resistance, and long-lasting sharpness. Combined with the blade’s slender geometry, it performs well in everyday cutting tasks.
Sheepsfoot and flat grind
The Sheepsfoot profile provides excellent edge control and a stable tip during practical use. The flat grind facilitates efficient cutting through materials and is well-suited for a lightweight EDC folder.
Gray PVD coating with a stonewashed finish
The blade is coated with gray PVD and then finished with a stonewashed effect. This combination gives the surface a matte, technical look and helps minimize the appearance of minor signs of wear.
Gray-Black Vortex Micarta
The handle is made of Vortex Pattern Micarta in a Black & Gray color scheme. The layered structure of the material creates a distinctive pattern, and its texture ensures a good grip while keeping the overall weight of the knife low.
Skeletonized Ti-6Al-4V liners
The internal structure of the handle consists of skeletonized Ti-6Al-4V liners. Removing excess material reduces weight without sacrificing rigidity, which is one of the key features of the AirTi series.
Kizer Clutch Lock™ with adjustable operation characteristics
Kizer Clutch Lock™ provides two-handed operation and a secure lock on the blade. The adjustable internal spring system allows the mechanism’s operation to be tailored to the user’s individual preferences.
Thumb Stud and Ball Bearing
The Thumb Stud enables comfortable one-handed opening, while the ball bearings support smooth blade movement. The mechanism complements the lightweight, slim design of the Madrac CL AirTi.
Reversible clip and black spacer sleeves
The stainless steel clip can be moved to the right or left side in the tip-up configuration. The Handle is complemented by black stainless steel spacer sleeves, which emphasize the folder’s open and lightweight design.

Frequently Asked Questions
Why is the Madrac CL AirTi so lightweight?
This model features a skeletonized Ti-6Al-4V liner and a lightweight Vortex Micarta handle. This allows for a reduced weight without sacrificing a full-size grip.
What does the Gray PVD Stonewashed finish offer?
The gray PVD coating creates an additional protective layer, while the stonewashed finish gives the surface a more rugged look. This combination also helps minimize the visibility of minor signs of wear.
How do you care for M390 steel?
M390 is corrosion-resistant, but after contact with moisture, it’s a good idea to clean and dry the blade. Diamond and ceramic sharpening systems work well for sharpening.
